Source Says: If latest rumours regarding next generation hardware are to be believed, the next PlayStation is to be significantly more powerful that the next Xbox.

Developer sources, speaking after meetings at CES, have told VG247 that the next PlayStation, codenamed Orbis, will have a run-capability of 1.84 teraflops. Conversely, the next Xbox, codenamed Durango, will be able to achieve 1.23 teraflops.

If true, these numbers mean PlayStation 4 will have a 33% raw, computational power advantage over Xbox 720.

While PS4 will have greater grunt that 720, however, the Microsoft machine has significantly more RAM at 8Gb, we've been told. Our source said that 3Gb is reserved for the OS, apps and security, leaving 4-5Gb for games.

Orbis will have 4Gb of RAM, said our source, of which 1Gb will be reserved for for OS, security and apps, leaving some 3Gb for games.

Both machines will supposedly have have the ability to read 100Gb Blu-ray discs.

Durango is apparently based on the Radeon HD 8770 GPU.

PlayStation 4 has been previously rumoured to be built on AMD's A10 APU, but VG247 has today been told the final machine will include both the APU and a second, discrete GPU.
